Thanks Vanilla and interestingly it was also the other way around for me in the past too, at the start of Peri hell. By nature I tend to want to understand, diagnose and fix, but I appreciate that that's not always possible in Peri - it's something about myself I'm still trying to work on, the "go with the flow"

I think because on my bad days I feel SO bad - can't work or do anything except lie on the sofa - which doesn't really mix well with a very high pressured job! I think the down days would be easier to cope with I was retired and could just give in to them, and I imagine this is how some mums here also feel - it's all the responsibilities we have that make it worse!
In the last three months my cycles have become a bit longer/more erratic - not a very long timeframe, but I have noticed it and it seems to have coincided with the feeling rough at the start of the cycle. After about 3 or 4 years of shorter and very regular cycles, ovulation is now starting to be delayed, so I wonder if I'm starting to move into the next phase. Do you experience any problems in taking Utrogestan outside of your normal cycle rhythm? I realise that's what 99% of ladies do anyway, I just haven't reached that stage yet and wondering how it will work!
